ATENT FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 438,287, dated October14, 1890.

Application filed May 9, 1890.

Toall whom it may concern:

Be it known that l, ROBERT L. HAWKINS,'a

^ citizen of the United States, residing at Dadeville, in the county ofDade and State ot' Missouri, have invented a new and useful Flour- Bolt,of which the following is a specification.

This invention relates to Hour-bolts; and it has for its object toprovide a device of this class which shallbe simple in construction, andby means of which the flour, while in the process of being bolted, shallbe thoroughly stirred and agitated, thus causing all of the flourparticles to pass through the boltingcloth.

A further object of the invention is to so construct the reel as toavoid any violent concussion of the chop.

With these ends in view the invention consists in the improvedconstruction, arrangement, and combination of parts which will behereinafter fully described, and particularly pointed out in' theclaims.

In the drawings, Figure 1 is a side elevation of a bolting-reel equippedwith my improvements, part of the casing having been broken away for thepurpose of exposing the construction of the reel. Fig. 2 is a transversesectional view taken on the line 2 2 in Fig.`1. Fig. 3 is a transversesectional View taken on the line 3 3 in Fig. 1. Fig. 4 is a longitudinalsectional View.

Like numerals of reference indicate like parts in all the figures.

1 designates the frame or casing of the reel, the ends of which areprovided with bearings for the shaft 2, which is provided with heads.

3 3, connected by longitudinal ribs 4, to the outer sides of which thehoops 5 are secured, said hoops being sunk in recesses or mortises inthe outer sides of said ribs, so as to be ilush with the latter.

6 designates a solid drum or body, which is mounted securely upon theshaft 2 intermediately between the heads 3 3. Said drum or body is made,preferably, of ashape of an eightrayed star in cross-section, as shownin the drawings hereto annexed, and the longitudinal ribs 4 arepreferably four in number. The bolting-cloth, which is designated by 7,is tacked or otherwise secured to the heads or ends and to the ribs,said cloth being stretched from the head to the tail end of the machine,

SerialNo. 351,147. (No model.)

so as to avoid the objectionable twisting of the cloth which frequentlyoccurs in reels of this description.

The casing 1 is provided at one end with an inlet-spout 8 and at theother end with an outlet-spout 9, and the shaft 2 is provided withspiral conveyers 10,. extending through the said spout-s to feed thechop into the bolting-reel and to convey the middlings away from thelatter. The bottom of the casing is divided into two separatecompartments, (designated by 11 and 12,) in each of which a spiralconveyer 13 is located. The compartment 11 receives the flour as itpasses through the bolt, and the compartment 12 may be suitablyconnected with the discharge end of the reel to receive the middlings,which may thus be reconveyed to the front end of the machine for thepurpose of subjecting the same, if desired, to a repetition of theoperation.

v The star-shaped drum or body of the reel is provided at the inlet endwith arms 14, eX- tending to the adjacent head 3. At the discharge endof the reel between the drum 6 and the adjacent head 3 are placedthebuckmiddlings are conveyed into the dischargespout.

Each of the longitudinal ribs 4 of the reel is provided on its innerside with a plate or iiange 16, forming a cap or bucket, by means ofwhich the contents of the reel is lifted on the upward movement anddischarged upon the bolting-cloth on the down side.

The drum or body 6 of the reel is provided with a series of agitators17, extending longitudinally through the entire length of the reel fromthe head 3 at the inlet end to the bucket-plates 15 at the opposite end,said agitators consisting of strips of coarse wirecloth or coarse radialwires interwoven with finer wires, as clearly shown in the drawings.These devices serve to thoroughly stir and agitate the contents of thereel during the operation of the device.

The operation and advantages of my invention will be readily understoodfrom the foregoing description taken in connection with the drawingshereto annexed.

The chop is delivered from the inlet-spout 8 into the space between thedrum 6 and the adjacent head 3, and it naturally drops down ets orradial plates 15, by means of which the into the lower part of the reel,the arms 14 serving to break the fall and to distribute the chop as itdrops. By the rotation of the latter its contents Will be thoroughlystirred and kept in constant movement by the agitators 17. The caps orbuckets 16 upon the longitudinal ribs 4L serve to lift or elevate thecontents of the reel and to discharge it upon the buckets formed by therecesses in the sides of the star-shaped drum, and thence onto thebolting-surface, along Which it slides, thus being thoroughly bolted orsitted. The advantage of the star-shaped drum or body Will be readilyunderstood, the sides of the same forming buckets to receive the chopfrom the buckets 16, the chop being thus not only thoroughly agitated,but also discharged upon the bolting-surface less violently and inabetter condition for sifting through than would otherwise be the case.Vhen the contents of the reel Areaches the discharge end, the buckets 15Will elevate and discharge it. into the spout 9, the spiral conveyer inwhich serves to discharge it.

The construction of my improved boltingreel, as Will be seen in theforegoing description is very simple and inexpensive, and it has provenin practice to be exceedingly useful and efficient.

Having thus described my invention, I claim- 1. The combination of thecylindrical reel, the interiorly-arranged star-shaped drum or body, andthe longitudinal ribs having caps or ianges on their inner sides,substantially as and for the purpose set forth.

2. The combination of the cylindrical reel, the interiorly-arrangedstar-shaped drum or body, the longitudinal ribs having caps or anges ontheir inner sides, and the longitudinally-arranged agitators, of coarseWirecloth or analogous material, substantially as set forth.

3. The combination, with the cylindrical reel, of theinteriorly-arranged star-shaped drum or body having arms extending tothe head at the inlet end, the radial plates or buckets arranged betweensaid drum or body and the head at the outlet end, and thelongitudinally-arranged agitators, of coarse Wirecloth, substantially asset forth.

4. The combination of the casing, the inlet and outlet spouts, thecylindrical reel mounted upon the shaft, having spiral conveyersextending through said spouts, the star-shaped drum or body arrangedWithin the reel and having arms extending to the head at the inlet end,the plates or buckets arranged between the drum or body and the head atthe outlet end, the plates or flanges secured upon the inner sides ofthe longitudinal ribs of the reel, and the longitudinally-arrangedagitators, of coarse Wire-cloth or analogous material, all combined andarranged substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

ROBERT L. IIAWKINS.
